A radial-flow exhaust-gas turbocharger turbine is provided with a row of adjustable guide blades which are rotatable via adjusting shafts mounted in a casing. The guide blades are each provided with sealing discs on their longitudinal sides running at right angles to the adjusting-shaft axes. The diameter of the sealing discs is a multiple of the thickness of the guide blades. The sealing discs which are located on the side remote from the adjusting shafts form bearing points for the guide blades in the casing.
